I have what i think is a unique issue. I purchased and installed the Autodesk Entertainment Creation Suite Ultimate 2013 without incident several weeks ago. Being new to AutoDesk, I sought to set up teh Brekel MOCAP software to work with Motion Builder (MoBu). Since it didn't work (apparently) with my 64bit installation, I decided to install the 32bit version. Since I have done similar with Adobe and a few other products I figure it wa no big deal. When Brekel seemingly behaved the same with teh 32bit version, i decided to remove the 32bit version. And that's whem I had problems.
I was stunned to discover my 64bit version wa sno longer considered registered and licensed. I attempted to re-register it to no avail. I uninstalled it and reinstalled it but got the same claims that my serial number was invalid. The nice folks at customer service have patiently outlined the process more than once to get me back up and registered. But their advice which is teh same as I'd already done isn't working.
What I did:
1. Unisntalled MoBu.
2. reinstalled MoBu and tried activating withmy existing suite S/N
3. I took screen shots of my software info and customer service4 advised me to
do what i had already done but I did it anyway and ended up with the same results.
Result: My S/N is considered in valid.
